Together We Stand June 20, 2007Posted by gordonwatts in physics.
Listening to a Higgs talk yesterday talking about prospects for a Standard Model Higgs search in 4 fb-1 and 8 fb-1 of data (2008 and 2009 results) one realizes that neither experiment can really do the job alone. Together, the two experiments can do a lot and cover a rather broad mass range. But apart neither of us are going to be able to do all that much. The Higgs is just too hard to find!
Combining results is difficult. It is difficult because of errors. When DZERO says that it has a 20% error due to Jet Energy Scale, is that really the same error that CDF reports as its Jet Energy Scale? In all likelihood, the answer is no. To do the combination properly is key to get these sorts of thing right and clear. This will require quite a bit of collaboration between the two experiments. Together, we have a chance of ruling out large stretches of the low mass range of the Standard Model Higgs: exactly the area the LHC has the most difficulty with.
I can’t wait.
